Avoid metal scrap in manufacturing.jpg

High-Performance Precision Castings for Maximum Yield

Scrap and rejections cost money  in time, rework, machining, and lost reliability.

Alloy Expertise

Our process is engineered to minimise variability, giving you repeatable parts, stable tolerances, and higher first-pass yield.

We consistently achieve:

As-Cast Tolerances
 

  • Typical: ±0.005 inch (±0.13 mm)

  • Standard compliance: ISO 8062 DCTG4–6 / VDG P690 D1–2

  • Tolerances depend on geometry, section thickness, and alloy shrink characteristics.

Post-Machined Tolerances
 

  • CNC machining: ±0.01 mm (geometry dependent)

  • Surface finish: down to Ra3.2

Performance Examples
 

  • Complex impellers with narrow passages held at 0.55–0.93 mm deviation, tighter than the customer specification of ±1.0 mm.

Engineers choose us for stable, predictable quality, batch after batch.

Consistent patterns, consistent castings.

  • CNC metal tooling designed for predictable shrink rates

  • Alloy-specific shrink factors (316L, Duplex, martensitic, nickel-base)

  • Optimised gating to eliminate porosity and cold shuts

Reduction in distortion, shrinkage variability, and inclusions.

  • Tight control of wax temperature, viscosity, and injection pressure

  • Automated shell building with monitored humidity & pH

  • Shell thickness validated for structural stability

Every intricate part undergoes digital gating simulation to avoid:

  • Hotspots

  • Shrink porosity

  • Flow defects

  • Thermal gradients that distort geometry

We use spectrographic analysis to keep every batch within spec:

  • Minimises micro-shrink and hot cracking

  • Improves mechanical properties

  • Reduces post-treatment distortion

Inspection That Prevents Scrap; Not Just Detects It

  • In-process measuring of wax patterns

  • Shell integrity checks

  • Melt & pour controls

  • Post-cast visual inspection

  • NDT (X-ray, PT, MT) for critical components

  • Full CMM dimensional reporting where required
